| 内容記述 | Three series of model are prepared to examine what factor controls the precision of strain where the axial ratio of initial strain marker ellipsoids is assumed to scatter as a normal distribution. The average method is used to analyze the 3D strain of the present simulation. Three series of model are produced to test three factors; (1) sample size of markers, (2) mean of axial ratio of makers and (3) standard deviation of axial ratio of markers. The simulation is performed in three deformational fields; pure shear of plane strain, isochoric transpression and simple shear of plane strain.

| 内容記述 | passiveな楕円体の歪マーカーを用いた平均法による３次元歪解析の精度が、初期歪マーカー楕円体の軸比が正規分布する場合に、３つの因子（1）マーカーの数（2）マーカーの軸比の平均（3）マーカーの軸比の標準偏差、とどう関係しているかを調べた。変形場としては（i）純粋剪断（ii）体積変化のないtranspression（iii）単純剪断、の３つを仮定した。結果は（1）歪マーカーの数が多いほど歪解析の精度が高い。しかし歪マーカーの数が300をこえると精度に変化はない。（2）歪マーカーの軸比の平均が１に近いほど、歪解析の精度は高い。（3）歪マーカーの軸比の標準偏差が小さいほど歪解析の精度は高い。これらの結果は３つの変形場でほぼ同様に成立する。しかしtranspressionと単純剪断では、変形につれ歪解析の精度は高くなるが、純粋剪断では変形につれて精度は変化しない。 | |||||||||
